There are actually only 6 wires on either side so it looks more daunting than it is. I don't know how it continued to run - some of the pins seem to be are missing and the male pin for the wire to the coil was not connected any more...

Anyway will order a suitable connector and once received put everything back together to see if the old coil and power transistor are up to snuff... Will update as to the outcome.

In the meantime thanks much for your support with this - persistence is helped a lot when there are two trying to solve the prob. B/Rgds
